Below the pinion is an inclined g'uideway in which is mounted aslide 16- also p'rovided'with rack teeth in engagement with the pinion pressure of the solerest 4 when the grippers and carrying at its upper end a last supporting member 18. A-spring 2O engaging at one end an abutment plate 22 on the arm 6 isarranged to force the slide 16 downwardly and. outwardly and thus to position this slide normally at its limit of downward V and outward movementand at the same- V timeythrough the pinion 14 to position the clamp member 10 at its inner limit of move- 7 ment relative to the arm 6. Accordingly, when the arms 6 are movedtoward the shoe the clamp members 10 engage the shoe before the supporting members: 18 engage it,

and the latter are; then moved up into engagement with the shoe by the action of the ,pinions 14: in the continued movement of the arms with relation to the members 10. The

members 18 are thus brought into position to support the last against-the downward release the upper and also a ainst the force of the tack drivers. In or er to lock each supporting member in operative position a ratchet wheel 24' is mounted to turn with the pinion 14 and a pawl 26. is arranged to engage this wheel and retain it in the posi-: tionto which itisftur'ned in :the upward movement of the slide 16. 7 The construction thus far described may be and is herein shown assubstantiallyidentical with that shown and described in the prior Patent No. 1,135,954, hereinbe forementioned.

In carrying out the objects of this invention, there are mounted on the upper clamping means, comprising the supporting arm 6 and the member 10at each side of the shoe,

wipers 28 for the purpose of laying theup per over the margin of the sole and the bottom of the last inf position to be tacked,

These wipers are "carried by holders 29 slidable in a guideway. in the clamp holder '12,

and springs 32 tensionable in a direction v substantially parallel'to thedirection of the movement of the side clamping means toward the shoe are arranged to position the wipersnormally in advance ofthe clamp member '10, as shown by full lines in Fig. 2. Accordingly, upon the inward movement of the arm 6, the wipers 28 will engage the upper of the shoebefore the clamp member 10 engages it, and since the upper atthis time-is held undertensionby the grippers '2 in the position shown, the wipers will be restrained from movement to operative position' over the last: bottom. The arm 6 will continue to move, however,'until the membars 10 and 18 are both firmly-engaged with the upperon' the last, such movement ofthe arm with relation to the wipers serving to compress the'springs 32. The parts will then be positioned substantially as indicated this figure, the iorce of the springs 32 may be such as to bend the upper to some extent between the grippers and the last, thus further tightening the upper on the last.

I During the finalstage of the cycle of operations of the machine inward movement is imparted to the grippers 2 and the tacker in dotted lines'in Fig; 2. 'AS illustrated by arms 8 in the usual manner to overdraw the 'upper. andv to position ,the tackers over the margin of thesole on the bottomotf the last, and during such movement the tacker arms finally trip the grippers 2 and cause the latter to release the upper. As the upper is thus overdrawn and finally released the springs 32 force the wipers 28inward and cause them to wipe the upper over and lay it firmly upon the margin of the sole on the bottom of the last, the-wipersv cooperating with the clamp members 10, and the shoe supports 18 ;to retain the tension of the upper in the brief interval between its release 1 by the grippers and the driving ofthe tacks.

The wipers, moreover, are so positioned relatively to the supports 18 that. the last'is held firmly between the wipers and the supports'and the wipers are caused to press the upper firmly ,on' the sole. The continued movement of the'tacker arms brings them last, andtwowipers 28 and-"springs 32 also v I are provided at eachside, one for each pair of jaws, the two wipers and their holders 29 being mounted side byside and movable independently of each otheron the clamp slide 12 in order to permit them to conform readily to variations in the contour'ofthe last. It will be understood, however, that the invention is not restrictive with respect to the particular number of the wipers or otherp'arts, and moreover that in its broader aspects the invention is not limited to mechanism for opereting inany particular:

position along the margin of the last, the expression lateral surface of the last being, used hereinto distinguish from thebot= tom and top surfaces without reference to any particu ar portion of the lateral periphcry. 7 V c Having described the invention, what I claim as new and desire to secure by Letters Patent of the United States is:
